In the second, you're joining two tables, but you're still using the same WHERE clause, products.userID = $userID. This is causing multiple records to be returned, since there is nothing specifying how you are joining the users and products table so it correctly returns a match for every row in the user table. Change the where clause to: WHERE products.userID = $userID AND users.userID = $userID and this will force the query to limit results to those records in products that have a matching record in the users table.

Hello PartyPosters, Tuesday, April 12, 2005, 4:24:34 PM, you wrote: P I can't figure out what I am doing wrong, this sql string seems to P filter out the information I want but it duplicates the all info, P as 'num_rows' is total of rows in the table and not the correct P value of the filtered information? P $sql=SELECT products.productID, products.title, P products.number_per_box, products.stock_level, products.image, P users.username, users.email, users.userID FROM users, products P WHERE products.userID = $userID; P $mysql_result=mysql_query($sql,$connection); P $num_rows=mysql_num_rows($mysql_result); Your query should probably be performing a join. As it stands you're selecting all of the products where userID = $userID, but you're also selecting all of your users regardless (SELECT blah FROM users). What relationship does the Users table have to the Products table? You may need something more along the lines of: SELECT blah FROM products LEFT JOIN users ON users.UserID = products.UserID WHERE users.UserID = $userID But that's just a best-guess based on what you've given so far.

---John Holmes...
ok, here's the code:
the form submits the user name and password in the variables $user and $pw to
another site, which includes this:
if(isset($user) isset($pw)){
$user = ucwords(strtolower($user));
$PHP_AUTH_USER = $user;
$PHP_AUTH_PW = $pw;}
if(isset($PHP_AUTH_USER)){
$result = mysql_query(select * from _users where user = '$PHP_AUTH_USER');
$_user = mysql_fetch_array($result);}
if(!isset($PHP_AUTH_USER)) {
header('HTTP/1.0 401 Unauthorized');
echo('unauthorized');
exit;}
else{
$result = mysql_query(select * from _users where user = '$PHP_AUTH_USER') or
die('Error occured while connecting to database');
$rows = mysql_num_rows($result);
if($rows == 0){
header('HTTP/1.0 401 Unauthorized');
echoscriptwindow.location.href='../index.php?action=user_wrong'/script;
exit;}
else{
$daten = mysql_fetch_array($result);
if($PHP_AUTH_PW == $daten['pw']){
// authorized
}
else{
header('HTTP/1.0 401 Unauthorized');
echoscriptwindow.location.href='../index.php?action=pw_wronguser=$user'/script;
exit;}}}
And this works fine for just this page. Whenever I click on a link to a page
which includes the same file though, it echoes 'unauthorized'...

Sounds like you're using sessions... perhaps register_globals is off in
your environment, so session variables are not registered? How do you set
the $user and $pw variables?

no, im not using sessions and register globals is on.
the variables user and pw are set by submitting a form (method=post). that's
where i expect the mistake to be. because as far as i know, the browser usually
saves the credentials, at least the user name after authenticating. but it just
doesn't seem to do so

Re: [PHP] Simple problem
I need insert some variable ito log.txt file but every item (variable) must be on other line how to do this ? If I am understanding your question correctly, you need to add a newline character (\n) at then end every line.
